Dry Farming - Truth or Hype?

DebRVA thought this was worth mentioning said

I recently heard about the reported benefits of dry farming: little/no sugar (and therefore fewer calories); organic and biodynamic farming techniques are better for the environment; natural yeast; no artificial additives; and lower sulfites. Just curious what my fellow Casemates think, and how much (if at all) it factors into the selections offered and purchasers’ decisions.
